predominates, and the tumor is of hard consistence and
slow growth. (3) Encephaloid cancer, {Medullary

element predominates, and the tumor is soft, grows
rapidy, and often ulcerates. (4) Colloid cancer, in
which the cancerous structure becomes gelatinous. The
last three varieties are also called carcinoma.
